What Are Cluster Pay Slots?

20 January 2023

If you are a player switching from the traditional slot machine to playing online casino slot machines, you have a lot to learn, ranging from ‘where to play’ to ‘how to play.’ This is because of the numerous unique slot machines online with different playing features and structures.

Some of these slot machines award jackpots progressively to players as they win. Some slot machines have the feature of playing games with free spins bonuses, while others offer picking bonuses and wheel spinning bonuses. With slot machines, the fun is endless, but the structure or design of a slot machine’s base game determines whether the player would find it interesting.

This article will discuss a specific type of slot machine with a unique playing structure- THE CLUSTER PAY!

What is Cluster Pay?

Cluster pay slots are an online slot machine that differs from traditional slots in how winning combinations are formed. Rather than relying on traditional slot paylines, cluster pay slots award wins when a cluster of symbols that appears on the reels.

This means that rather than symbols appearing in a specific pattern on the reels, as is the case with traditional pay lines, a cluster of symbols anywhere on the reels can result in a win. The critical point to remember is that these symbols must be next to each other and touch one of the four sides.

Each of these symbols determines the payouts, and the greater the clump you can obtain the higher your payout. NetEnt first introduced the cluster pay payment system used in cluster pay slots with the online slot Aloha, which we will discuss later.

Advantages of Cluster Pay

One of the main advantages of cluster pay slots is that they can offer players the chance to win more frequently than traditional slots. This is because the cluster pay mechanic allows for multiple wins on just a single spin as long as the clusters of symbols meet the requirements set out in the game’s paytable.

In addition to the potentially higher and frequent wins, cluster pay slots are more visually appealing than traditional slots. This is because the cluster pay mechanic allows for the symbols to be placed in a more dynamic and visually striking way on the reels. Thus, this creates a more immersive and engaging gaming experience.

How Cluster Pay Slots Pay and Play

The playing structure, which is unlike other types of slot machines, does not involve discovering any pay lines attached to a pay slot. All you have to do as a player is to focus on forming winning combinations when playing since the designers of cluster pay slots have done away with pay lines.

If you are wondering how to form winning combinations when playing on a cluster pay slot machine, you have to spin in a matching set of symbols on the reel. You can do this anywhere on the slot game screen in a way that a group of at least a set of matching symbols is in a cluster. The more matching reel symbols you have, the more wins you stand to get.

Can a Player Really Win Much from Cluster Pay?


When it comes to payment, online cluster pay slots offer players the chance to win big prizes by landing clusters of symbols on the reels. But just how much can you win at these games?

The amount you can win at an online cluster pay slot depends on several factors, including the size of the cluster, the value of the symbols in the cluster, and any multipliers that may be in play. Some cluster pay slots also have progressive jackpots, which can offer even larger payouts to lucky players. It’s helpful to look at some examples to give you an idea of the potential payouts at online cluster pay slots.

A cluster of 10 symbols may payout 100 times the bet, while a cluster of 20 symbols may payout 500 times the bet. Of course, these payouts will vary from game to game, and some may offer even higher payouts for larger clusters. It’s worth noting that the maximum payout at an online cluster pay slot is usually capped at a certain amount.

This means that even if you land a massive cluster with a huge multiplier, you may not be able to win more than the maximum payout. Overall, the amount you can win at an online cluster pay slot will depend on the game you’re playing and your luck on the reels.

However, with the potential for big payouts and exciting special features, these games offer plenty of opportunities for players to win big.

If you want to have an idea of how much you stand to win by playing an online slot with cluster pays features, here are a couple of things you may need to do:

  1. Know your volatility; your cluster pay slot variance. This tells you how often you can win.
  2. Find out the RTP of the cluster pay slot because every slot comes with its unique RTP. This will guide you in knowing the percentage of wins a slot will give you. The average RTP for cluster pay is 96.42%, and even though it differs for each online slot, they are usually fair enough for players.
